This Small Business Innovation Research (SBIR) Phase I project focuses on the implementation of a Terahertz (THz) module that can emit coherent and tunable Terahertz waves. This project naturally follows the recent result obtained by the Project Investigator. Recently, coherent Terahertz radiation… More

"This SBIR Phase I project focuses on the implementation of a new THz module that can emit coherent and tunable THz waves. Recently, coherent THz radiation was generated at room temperature by PI, with a tuning range of 56.8-1618 ¿m (5.27 - 0.18 THz), inGaSe based on difference-frequency… More

This Small Business Innovation Research (SBIR) Phase I project focuses on the implementation of a blue-light converter based on a novel structure of KTiOPO4 (KTP) crystal. It proposes to integrate quasi-phase-matched (QPM) second-harmonic generation (SHG) with 90 degrees phase-matched… More

This SBIR Phase I project focuses on the comprehensive analyses and designs of the three novel prototype THz-frequency spectrometers. Such a goal is built upon the recent success of the implementations of widely-tunable monochromatic THz sources and the accomplishments of chemical sensing,… More

This SBIR Phase I project focuses on the implementation of a novel THz spectrophotometer. Such a goal is built upon the recent success of the implementations of widely-tunable monochromatic THz sources and the characterizations of Bragg reflectors and bio tissues. During the Phase-I period, we… More

By continuing teaming up with one of the most reputable university teams in THz science and technology, ArkLight proposes to carry out the tasks set for a Phase-II program following our success in Phase I. We are aimed at the further development of novel spectrometers to analyze chemicals in the… More

In the proposed work we will investigate the THz properties of a slab waveguide made from a GaP or ZnGeP2 wafer. We plan to investigate how the width of a slab waveguide will affect the output power of the THz waves and normalized conversion efficiencies. We are particularly interested in the… More

In this Phase II proposal from the ArkLight/Lehigh team, we propose to investigate variety of semiconductor and polymeric electro-optic crystals and materials with one of our goals for scaling up the output powers of the THz sources. We are going to explore a class of the novel THz components… More

PI at ArkLight proposes a novel approach to photon counting detectors at near-IR (1-1.8

PI at ArkLight proposes to implement photon counting detectors at near-IR (1-1.8 microns) and mid-IR (3-4 microns) with single photon sensitivity based on frequency up-conversion during Phase 2, representing an innovative Lidar technology for ASCENDS mission. By working with Prof. Ding at Lehigh… More

PI at ArkLight proposes a novel scheme for making cloud discrimination in the wavelength ranges of near-IR (1-1.8µm) and mid-IR (3-4 µm). This scheme is based on optical phase conjugation from a second-order nonlinear medium. It overcomes the disadvantages of slow speed in photorefractive… More

By closely working with Prof. Ding"s group at Lehigh University, PI proposes to take a revolutionary approach to THz generation based on difference-frequency generation. Such a nonlinear process will take place inside the cavity of a dual-wavelength Yb:YAG laser. PI plans to demonstrate… More
